C++ side effects

hi All

the following comes from c++ standards:

"Accessing an object designated by a volatile lvalue (3.10), modifying
an object, calling a library I/O
function, or calling a function that does any of those operations are
all side effects, which are changes in the
state of the execution environment."

According to this definition, consider this function,

T ReturnT(){
    T result_;
    //do something
   return result_;    // #1
}

At #1, I think
1) if T is scalre type such as int or char, the returning sentence
would not have side effects
2) if T is a class type,  does returning type T have side effects? and
Why?

Thanks
Chang
